Authorities are questioning several people as they try to determine any possible connection between an explosion in a bustling New York City neighborhood, an unexploded pressure-cooker device found blocks away and a pipe bomb blast in New Jersey.

FBI spokeswoman Kelly Langmesser says agents stopped "a vehicle of interest in the investigation" of the Manhattan explosion Sunday night. She said no one has been charged.

Gov. Andrew Cuomo said the Saturday night blast in Manhattan that injured 29 people didn't appear to be linked to international terrorism.

Cell phones were discovered at the site of both bombings. Authorities say the New York City bomb contained residue of an explosive often used for target practice that can be picked up in many sporting goods stores.
